MECHANISMFORRABBLING MATERIALS.

SPECIFICATION forming' part of Letters, Batent No. 740,103, datedSeptember 29, 1903. Application filed November- 1, 1902. Serial No.129,699. (No model.)

To all whom it may concern:

Be it known that I, ALFRED J. DIESCHER, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements inv Mechanism for Babbling Materials, of which improvementsthe following is a specification. The invention described herein relatesto certain improvements in furnaces for roasting ores, &c., and inmechanism for rabbling the material and causing a gradual progressivemovement of the material through the fur nace.

The invention is hereinafter more fully described and claimed. Y

In the accompanying drawings, forming a part of this specification,Figure 1 is a sectional elevation of a roasting-furnace having myimprovements applied thereto. Fig. 2is a sectional plan of the same.Fig. 3 is a sec tional plan of a portion of the furnace on an enlargedscale, showing the rabble. Fig. 4 is a sectional elevation on a planeindicated by the line IV IV, Fig. 1. Fig. 5 is a plan View of thecentral portion-of the rabble-carrying wheel. Fig. 6 is a sectionalelevation of the same on a plane indicated by the line VI VI, Fig. 5;and Fig. 7 is a detail View, on an enlarged scale, illustrating themanner of connecting the rabble tothe draft-rope.

In the practice of my invention rails 1 and 1 are arranged in thefurnace contiguous to the side walls for supporting the frame 2 of therabble. The frame is provided at its ends with wheels'3, adapted to movealong the rails. As shown in Fig. 2, it is preferred that the end of theframe moving along the outer or larger circle should have twosupporting-wheelsto prevent tippingof the frame,

while the opposite or inner end is provided with only one wheel. The useof only one wheel atthe inner end isnot essential, but

only convenient as regards the connection of the frame with thecarrying-wheel, as hereinafter described. a

In order'to prevent the material'from interfering'with the movementofthe wheels on" to the rope by a mechanism consisting of a block 5,pivotally connected to the frame, and a bar 6, pivotally connected tothe block. These pivotal connections are so constructed and arrangedthat the outer end of the bar isfree to swing vertically andhorizontally. The head 7 on the outer end of the bar 6 is slotted forthe passage of the rope and for the reception of the rope-grippingdevices, which consist of stationary and movable blocks 8 and 9, alongitudinally-movable wedge-block 10, and the operating-handle 11. Thishandle is preferably made in the form of a bell-crank pivotally mountedin the head and having one arm in engagement with the wedge, while theother arm extends forward in line, or substantially so, with the bar.

j The rope. 12 moves along a channel-way formed by the retaining-walls13 and is supported, except when in tension, by pulleys 14, looselymounted on standards 15, arranged in' a tunnel 16, extending along underthe channel-way. The upper portions of the peripheries of the pulleysproject through slots in the bottom plates of the channel-way. It willbe observed that the rope is entirely above the tunnel, being at all.times in the channel, the side walls of which tend to protect the ropefrom excessive heat,

In order to transfer the rabble-frames from one side of the furnace tothe other, I arrange two turnin g-tables at each end of the furnace, asshown in Figs. 1 and 2, one continuous line of rails having two halfcircles and straight portions and short sections of rails. Theturn-tables, which support and carry the rabbling-frames from one lineof tracks to'the other, are provided with two rims 'oi' peripheries 18and 19, and the tables are so propor tioned and arranged,-as showlrinFigs. 2, 5,

and 6, that a line coinciding with the longitudinal axis of the furnacewill be tangential to the outer rims or peripheries 18 of the tables andthe short railsections 20, which are prolongations or extensions of theline of rails 1, will be tangential, or approximately peripheries 18 ofthe tables, one or both of.

which are driven. The rims engage the rope frictionally or in anothersuitable manner to effect the desired movements of the rabbleframes.

As shown in Figs. 5 and 6, the rail-sections 20 are so arranged thattheir outer ends lie immediately above the inner rims 19, which areprovided with suitable means for engaging and supporting the end of theframe traversing the rails 1. In the construction shown the rims areprovided with the notches 21, suitable for the reception of the wheelstraversing the rails 1. As the frame is drawn along by the rope thewheel on the inner frame will drop from the rail-section 20 into one ofthe notches 21, and as the draft mechanism of the frame is at the sametime clamped to the outer periphery or rim of the table the frame willbe carried around thereby, the outer end of the frame being merelysupported by the curved section of rails 22 to prevent sagging down. Asthe table completes a half-revolution the wheel will be raised from thenotch in the rim 19 by the inclined extension 23 of the rail-section 24and pass onto said rail. At the opposite end of the furnace thisoperation is repeated except that the wheel will be raised from thenotch by the inclined extension 23 of the railsection 20. While theframes are between the turn-table they can be disconnected from the ropeand allowed to cool.

It is desirable that the draftrope should be maintained at about thelevel of the floor of the furnace, and to this end the turntables arearranged at such a height that the portion of the outer rim orperipheries 18, with which the rope engages, is on or approximately on alevel with the floor of the furnace, as shown in Fig. 1. Vith such anelevation of the turntable it is necessary to raise-the rabble in orderthat its inner end should engage the inner rim of the turn-table and tocorrespondingly lower the rabble-frame at the opposite end of thefurnace. This vertical movement of the frame can be conveniently done byinclining portions of the lines of track intermediate of the turn-tablesand the furnace.

As shown in Fig. 3 the blades 25 are arranged on the frames in twoseries, the blades of one series being preferably at an angle to thoseof the other series. In order to vary the transverse and longitudinalmovements of the material, it is preferred that the blades should bepivotally connected to the frames, so that their angular positionrelative to the direction of movement may be adjusted at will. \Vhilenot limiting the invention to any particular construction or arrangementof blade adjusting and hold mechanism, that shown in Fig. 3 has beenfound convenient. As therein shown the blades of one series areconnected together by a bar 26 and those of the other series by a bar27, the two series being connected by a bar 28. One of the bars,

as 27, can be used as an operating-bar, being extended at one endandprovided with means for engaging the frame, as holes in the bar, anda pin 29 on the frame.

I claim herein as my invention- 1. The combination of aroasting-furnace, a rabbling-frame, turning-tables at the ends of thefurnace for carrying or transferring the rabbling-frame and a trackconnecting said tables, substantially as set forth.

2. The combination of a roasting-furnace, a rabbling-frame, a continuousline of track passing through and outside of the furnace, a section oftrack passing through the furnace, turn -tables having rims, said tablesbeing so arranged at opposite ends of the furnace that the rims aretangential to the section of track, and a section of track outside ofthe furnace and intermediate of the tables and tangential to said rims,substantially as set forth.

3. The combination of a roasting-furnace, a rabbling-frame, a continuousline of track passing through andoutside of the furnace, for supportingone end of the frame, a section of track passing through the furnace, asection of track outside of the furnace, and

means for supporting and transferring the opposite or inner end of theframe from one section of track to the other, substantially as setforth.

4. The combination of a roasting-furnace, a rabbling-frame, a continuousdraft-rope passin g through and outside of the furnace, a 0011- tinuousline of track passing through and outside of the furnace for supportingthe outer end of the frame, a section of track passing through thefurnace, two turn-tables each provided with two rims, the tables beingso arranged that the rims are tangential to the line of movement of thedraft rope and the track-section respectively, the inner rims beingprovided with means for engaging the inner-end of the frame, and a tracksection outside of the furnaceand tangential to the inner rims of thetables, substantially as set forth.

5. The combination of a roasting-furnace, a rabbling-frame, a draft-ropepassing through and outside of the furnace, turn-tables each providedwith rims, the rim for engagement with the rope being in orapproximately in the plane of the floor of the furnace, and the other orinner rim being provided with means for engagement with the rope, andtracks extending from the furnace to the turn table, said tracks havinginclined portions, substantially as set forth.

In testimony whereof I have hereunto set my hand.
